Simply go into the holding page of one of the custom securities that you’ve been manually maintaining and go to the Holding Settings menu, which is down at the bottom, right-hand corner of the page.

Click the link to “Move to a Listed Instrument” and on the pop-up screen select the market (which corresponds to the country you originally selected when you created the custom security). Then search for the company by name or code. Click Save and voila!

Your old, previously manually maintained investment has now been merged into the real holding. Going forward all prices, dividends, and corporate actions will be handled automatically.
